The circuit consists of two astable multivibrators. Sound controlled light circuit diagram. This music rhythm operated dancing light circuit is based on transistor bc547. Block diagram of bi color led circuit. The speed of the dancing leds depend on the frequency of the clock pulses generated. This can be done through potentiometers vr1 and vr2 to produce different dancing pattern of leds. To create this circuit we have mainly used 555 timer ic and 4017 ic. Current from the positive of battery flows through first set of leds d1 d3 to the collector of t1 through resistor r1. The ic1 is wired as an astable multivibrator to provide the clock pulses for the cd4017. In this particular circuit we have created a pattern in which 6 leds are illuminating in forward and reverse order.
Duty cycle of each multivibrator can be varied by changing rc time constant. It is a simple astable multivibrator using two npn transistors. Flashing or dancing speed of leds can be adjusted and various dancing patterns of lights can be formed. Use a shielded cable to connect the microphone to the circuit. The leds turns on off alternately giving a dancing appearance. The speed of the dancing leds depend on the frequency of the clock pulses generated. The leds connected to these pins glow in the same fashion to give a dancing effect. By techgenie in circuits electronics. The potentiometer p1 p2 and p3 must have plastic shafts and knobs. This circuit is very simple and easy to build it just requires a few basic components.
Friends it a simple music operated. In this instructable i will tell you how to make amazing dancing lights so that you can build it up at home and even start your own disco if you have enough cash just kidding. How to make dancing led s. Basically these are designed to pick the high intensity sound like bass sound. So these lights follow the high pitch beats in music like drum. Generally we use small voltage bulbs in the dancing bulbs. One multivibrator is formed by transistors t1 and t2 while the other astable multivibrator is formed by t3 and t4. In this particular circuit we have created a pattern in which 6 leds are illuminating in forward and reverse order. The leds turns on off alternately giving a dancing appearance. The current through r1 charges capacitor c2.
It is a simple astable multivibrator using two npn transistors. Using only few and simple components you can. Friends in this video i will show you music operated dancing light circuit how to make a music rhythm led flash light. How to make dancing led s. So these lights follow the high pitch beats in music like drum. The current through r1 charges capacitor c2. Hello guys i am techgenie an electronics hobbyists tech tinker and developer. The components used must have enough ratings to deal with those. This circuit is very simple and easy to build it just requires a few basic components. I dedicate my free time in designing and making various creative and innovative projects rc toys incredible gadgets.
Sound controlled light circuit diagram. Generally we use small voltage bulbs in the dancing bulbs. To create this circuit we have mainly used 555 timer ic and 4017 ic. Friends in this video i will show you music operated dancing light circuit how to make a music rhythm led flash light. The leds turns on off alternately giving a dancing appearance. We can create many kind of dancing leds patterns for decoration. It is a simple astable multivibrator using two npn transistors. I dedicate my free time in designing and making various creative and innovative projects rc toys incredible gadgets. For each clock pulse receiving at the clock input pin14 of ic cd4017 the outputs q0 to q9 refer pin diagram of cd 4017 becomes high one by one alternatively. Dancing leds circuit is used for decorative purpose and looks very good when these leds glow in sequential manner.
